Here are a few Q's for anyone who can anser.
I want to make a copper piston valve using compression fittings, and not soldering. So...
1. Can the pipe slide through the fitting without modification? This is to make the seat, so whether I go with coaxial or tee, I need this option or I need suggestions to make the valve seat.
2. Are there such things as compression bushings, or will I have to use a short piece of pipe in the front port of the tee, to a reducer, in which the seat will go in?
Thanks in advance to anyone who can help.
